gcc45-pr41445.patch

Updated patch that actually passed bootstrap.  Unfortunately it regresses many
gcc.dg/cpp/ tests, e.g. avoidpaste1.c is now preprocessed as:
# 1 "../../gcc/testsuite/gcc.dg/cpp/avoidpaste1.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "../../gcc/testsuite/gcc.dg/cpp/avoidpaste1.c"
# 25 "../../gcc/testsuite/gcc.dg/cpp/avoidpaste1.c"
:: : : : : :^: 1.0e-
# 14 "../../gcc/testsuite/gcc.dg/cpp/avoidpaste1.c"
                        1
# 26 "../../gcc/testsuite/gcc.dg/cpp/avoidpaste1.c"
: : : .. . 0 0 .
